Summary

CrossWatch (CW) is a synchronization engine. Prior to version 0.9.21, GET /api/app-auth/status is accessible without authentication and returns the other_sessions array, which exposes metadata of all active sessions — including originating IP addresses, User-Agent strings, internal session IDs, and creation/expiry timestamps. Any unauthenticated network attacker can enumerate this data without credentials. Version 0.9.21 fixes the issue.

Risk Assessment

The risk is the disclosure of sensitive information about active sessions, which could allow an attacker to track users, hijack sessions, or conduct targeted attacks.

Recommendation

It is recommended to upgrade CrossWatch to version 0.9.21 or later to enforce authentication for this endpoint.
